There is a way but it's very very very complicated.
First you have to buy some chemicals (strong acids and methyl alcohol). Then you need precision mechanics tools, a Oscilloscope,a good Logicanalyser and a very good microscope.
After you got everything view this YouTube video: http://www.youtube.com/watch?v=tnY7UVyaFiQ
Nearly the same way you'll get the data out of the ATtiny2313.
If I get some other method's I'll post it here.
